Baselines.
For the baseline models, we used the released code of ONet [1]}, OFlow [2]} and PIFuHD [3]}, [4]}. For the static 3D reconstruction baselines (, ONet and PIFuHD), we re-train these models on all the frames from the training set using the default setting.
Note, the dynamic 4D reconstruction baseline OFlow always utilizes the initial frame for the canonical space.
Therefore, for a fair comparison, we set OFlow's first frame to be the center of our input clip.
